EDGE Analysis

Keller's last two seasons were spent with the Hanshin Tigers, with whom he posted a 2.59 ERA and 74:21 K:BB over 59 innings. The 30-year-old holds a career 5.83 ERA over parts of three seasons at the major-league level.

EDGE Analysis

Keller made a career-high 32 relief appearances with the Pirates during the 2021 campaign but sputtered to a 6.48 ERA and 1.56 WHIP in 33.1 innings. The right-hander will now attempt to right the ship overseas.

Keller cleared waivers and was outrighted to Triple-A Indianapolis on Saturday.

EDGE Analysis

Keller tossed a career-high 33.1 major-league innings this season but didn't look particularly good. He struggled to a 6.48 ERA, thanks in large part to his low 29.3 percent groundball rate and his high 14.2 percent walk rate.

The Pirates recalled Keller from Triple-A Indianapolis on Monday.

EDGE Analysis

Pittsburgh optioned Keller to Indianapolis a day earlier, but he'll be eligible to rejoin the Pirates on Monday after Luis Oviedo (undisclosed) was placed on the 10-day injured list in a corresponding move. Expect Keller to fill a low-leverage role out of the Pittsburgh bullpen during the final week of the season.

Keller was optioned to Triple-A Indianapolis on Sunday.

EDGE Analysis

Keller has been in the majors since early July -- not counting a one-day stint at Triple-A -- but will now head back to the minors. The 28-year-old has a 6.75 ERA, 1.53 WHIP and 29:20 K:BB across 29.1 big-league innings this season.

Keller was recalled from Triple-A Indianapolis on Sunday, Rob Biertempfel of The Athletic reports.

EDGE Analysis

The 28-year-old was sent down to Triple-A on Friday but will quickly rejoin the big-league roster with JT Brubaker (shoulder) and Duane Underwood (shoulder) landing on the injured list. Keller has a 7.13 ERA, 1.58 WHIP and 25:18 K:BB over 24 innings out of the bullpen for the Pirates this year.

Keller was optioned to Triple-A Indianapolis on Saturday.

EDGE Analysis

Keller had been on the big-league roster since early July. He recorded a respectable 4.00 ERA in 10 appearances that month but struggled to a 9.26 ERA in 10 outings in August. The transaction clears a space for the Pirates to activate Saturday's starter JT Brubaker (thumb) from the injured list.

Keller (0-1) took the loss Wednesday versus Milwaukee. He allowed two runs on a hit and a walk with one strikeout in two-thirds of an inning.

EDGE Analysis

Keller got two outs quickly in the seventh inning, but he allowed the next two batters to reach base on a single and a walk. Chasen Shreve was brought on to face pinch hitter Rowdy Tellez, but Shreve allowed a three-run home run, and the two runs charged to Keller were enough to stick him with the loss. The 28-year-old right-hander continues to produce inconsistent results in a low-leverage role. He has a 7.07 ERA, 1.64 WHIP and 17:11 K:BB through 14 innings this year.

Keller was recalled from Triple-A Indianapolis on Saturday.

EDGE Analysis

Keller spent over a month with the Triple-A club, and he posted a 2.20 ERA, 0.86 WHIP and 26:1 K:BB in 16.1 innings during his most recent stint in the minors. The right-hander has made three major-league appearances this year and should serve mainly as a low-leverage reliever going forward.

Keller was optioned to Triple-A Indianapolis prior to Tuesday's game against the Cubs.

EDGE Analysis

With Cody Ponce being recalled to start Tuesday's tilt, Keller was deemed the odd man out for the Pirates. The right-hander appeared in three games since being called up May 15, allowing three earned runs on two hits and three walks while punching out four. He figures to be a candidate to rejoin the big club at some point later this season.
